+ * assumes that pointer to CPU environment is stored in ebp register, which
+ * is true for calls made inside JIT, but is not necessarily true for calls
+ * made outside of JIT. The way SOFTMMU macros are expanded in this header
+ * enforces ldx/stx routines to use CPU environment stored in cpu_single_env
